Flexible distributed lag models for count data using mgcv
In this tutorial we present the use of R package mgcv to implement Distributed Lag Non-Linear Models (DLNMs) in a flexible way. Interpretation of smoothing splines as random quantities enables appr...

A nice tutorial on distributed lag models using #rstats 📦 {mgcv}. But if you want to fit these to time series you might want to consider the {mvgam} 📦 instead ecogambler.netlify.app/blog/distrib...

I wrote a thing about using the gratia 📦 for #RStats, which makes working with #GAMs and the mgcv 📦 a little easier and, dare I say, prettier
